Does Koch Rt2 Toyota / Mysa have drinking water violations?
Of the 12 most recent violations in EPA's records, 6 are health-based, and the most recent began in January 2022. The violations listed here began between July 2017 and January 2022. By type: 5 contaminant level above the legal limit, 4 monitoring, 2 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Revised Total Coliform Rule (5 of them). EPA lists 9 as resolved, 2 as archived and 1 as addressed. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed.

Addressed means the violation is not resolved or archived and is covered by formal enforcement.
